I think ToCs are usually their own page unless they are very short. And you don't submit the title page, so it's not relevant. You'd submit the manuscript with a cover page, ToC, and then the poems, one to a page unless you anticipate two being on the same page in the published work. The row of dots question probably depends on the publisher. If you have a publisher in mind, look at how they format in their published works and copy that. Collections are hard to sell. Good luck with it.
